Remedial sealant for homes and businesses in Bashley
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. If you are dealing with beads that never stuck properly and products that weren’t meant for the joint, we can put it right, on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints alike.
Somewhere as small as Bashley, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
There’s a 12-month guarantee on every job, large or small.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Do you need remedial sealant in Bashley?
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
It’s worth asking for a quote if you see:
- Sealant applied over old sealant that has lifted
- Leaks that keep coming back after resealing
- Mould trapped under a layer of silicone
- Torn expansion joints
Letting a property close to New Milton station? Then a joint that keeps failing is best fixed properly while the property is empty.
Questions to ask before booking
- Is VAT in the price?
- What happens if the job turns out different

What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you fix expansion and movement joints?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Remedial sealant in Bashley: local notes
Bashley is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Ballard School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around St John, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Aftercare tips
So the new joints stay in good condition:
- Ask why a joint failed before redoing it
- Don’t point over movement joints
- Report a tray that rocks or a worktop that lifts
- Deal with small splits early
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Landlords, agents and businesses in Bashley
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Letting agents and landlords in Bashley can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Other services in Bashley
What the job involves on each surface
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed in a colour to suit.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied, and we tell you how long to leave it before we go. Somewhere like Bashley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Mention any tricky access
- Tell us if parking is tricky
- Tell us about any water getting in
